NOZZLE CLOSURE AND CLEANER File d Aug. 17, 1943 Flgi Patented Dec. 5, 1944 Jesse E. Pitts, Houston, Tex. Application August 17,1943, Serial No. 498,989

2 Claims.

This invention relates to a nozzle closure and cleaner.

An object of the invention is to provide a device of the character described especially designed for use on fire extinguishers to keep the hose nozzle of the extinguisher from becoming plugged and which, at the same time, will allow the escape of gas,wl1ich accumulates in the extinguisher when not in use.

A further object of the invention is to provide a nozzle closure which will cleanse the nozzle when the latter is to be used.

Some types of fire extinguishers are equipped with flexible hose terminating in a discharge noz zle. When not in use the extinguisher is inverted and the hose hangs alongside the extinguisher. The nozzle sometimes becomes plugged up by the collection of foreign matter therein, particularly by the deposits made by insects such as mud daubers. At times the nozzle is completely closed so that the small amount of gas accumulating.

while the extinguished is not in use cannot escape causing the extinguisher to burst, and even though the nozzle is not completely closed it sometimes becomes so restricted as to operate inefficiently when it is sought to use the same. The

, closure herein described will not only exclude foreign matter but will allow the escape of accumulated gas and will wipe the nozzle clean when it is sought to use the extinguisher.

With the above and other objects in view the invention has particular relation to certain novel features of construction, arrangement of parts and use, an example of which is given in this specification and illustrated in the accompanying drawing wherein:

Figure 1 shows a side'view of a fire extinguisher in inverted position showing the nozzle closure applied thereto.

Figure 2 shows the anchor with means for rastening the sameon the extinguisher and view.

Referring now more particularly to the drawing, wherein like numerals of reference designate the same parts in each of the figures the numeral I designates a, conventional typeof lfire extinguisher which is shown inverted in Figure 1.

Figure 3 shows an enlarged vertical, sectional,

The extinguisher is provided with the stand 2 on which it rests when in use.

The extinguisheris inverted when not in use as ShOWIl.

A flexible hose 3 is connected into the bottom ofthe' container and its free end has the nozzle 4 attached thereto.

The hose and nozzle hang alongside the extinguisher when the latter is not in use.

An anchor 5 is attached, in any preferred manner, to the top of theextinguisher. As shown this anchor is adjustably mounted on theband 6 which may be secured around the extinguisher so as to position the anchor beneath the lower end of the nozzle. A cylindrical brush T has a universal connection 8 with the anchor and is of a diameter to fit snugly within the nozzle and is of such length as to extend well up into the nozzle. It is formed with stiff bristles which form a closure for the nozzle andwhich, at the same time allow the escape of gas which may accumulate in the extinguisher while the latter is stored.

When it is desired to use the extinguisher it may be inverted and supported on the stand 2 and in using the hose to apply the extinguishing 1 fluid the nozzle will be drawn ofi of brush 1 and will be open and free of allclogging foreign matter whichmight restrict the nozzle.

The drawing and descriptions are illustrative merely while the broad principle of the invention will be defined by the appended claims.

What I claim is:

1. In a fire extinguisher having a movable discharge nozzle; an approximately cylindrical brush formed of bristles extended into the nozzle and forming a closure therefor, said closure being connected to the extinguisher so as to be withdrawn from the nozzle, when the nozzle i moved to position for use.

2. In a fire extinguisher having a movable discharge nozzle; a brush formed of bristles extendedinto the nozzle and forming a closure therefor, said closure being anchored so as to be withdrawn from the nozzle when the nozzle is moved to position for use. l
